I have a broken DVD drive and no others available right now to burn a DVD iso to so I'd like to use a empty hard disk instead.
I've tried Unetbootin but that only copies a few megabytes of files - the rest of the image data in the ISO is ignored.
I have verified the ISO is valid and working with VirtualBox. It's MD5 hash is also as expected. But I need to boot at the real BIOS not an emulated one.
I've also tried things like:
sudo cat /disk/image.iso > /dev/sdb1
and that got "Permission denied" - no idea why.
